Just fill each Luminary Bag with a safe flickering LED Candle or super bright Submersible Light. NOTE: Luminary Bags with Happy Birthday Design DO NOT include lights. TIP: Add a bit of sand to the bottom of each bag if wind is an issue. Drop your LED light on top of small sand pile and *voila*. Bag Dimensions (W x H): 5.87″ x 10.75″
